Answer:
10 feet
Step-by-step explanation:
- Multiply 20 by 6 which will give the answer 120 (in inches).
- Then convert 120(inches) to feet by dividing with 12.
- The answer will be 10(feet) needed for six shelves.
20x6= 120
120/12=10
=10 ft

None of them are irrational, the definition of an irrational number is a number that cannot be simplified, converted to a fraction, or has no pattern to it or is never ending. For example, a pi is an irrational number because it is never ending and has no pattern to it. Another example would be 0.21411446741354... irrational because it has no pattern to it and cannot be converted to a fraction.
Answer:
By the Chebyshev Theorem, at least 75% of commuters in Boston has a commute time within 2 standard deviations of the mean
Step-by-step explanation:
Chebyshev Theorem
The Chebyshev Theorem can also be applied to non-normal distribution. It states that:
At least 75% of the measures are within 2 standard deviations of the mean.
At least 89% of the measures are within 3 standard deviations of the mean.
An in general terms, the percentage of measures within k standard deviations of the mean is given by
